Triathlon-specific bottoms differ from cycling shorts in a few key ways: the chamois is thinner and designed not to retain water during the swim, the fabric dries quickly, and the fit is streamlined for the run. One-piece trisuits and speedsuits offer the advantage of a single garment for the entire race, eliminating a top change in T1. For shorter races like sprint and Olympic distance, a trisuit is often the fastest choice; for long-course events, some athletes prefer the flexibility of separates.

Assos tops the lineup with the Triator speedsuit for riders who want a premium race-day garment. Orca offers tri shorts at multiple price points through their RS1 and Core lines. The 2XU Dark Shield trisuit and Cervelo Ego 2.0 skinsuit round out the one-piece options, while Oomph! speedsuits and Asics run shorts give athletes more choices for race formats and budgets.
